Osisko Metals Reports First Infill Drill Results at Gaspé Copper

MONTREAL, Aug. 04, 2022 -- Osisko Metals Incorporated (the " Company" or " Osisko Metals ") ( TSX-V: OM; OTCQX:

OMZNF; FRANKFURT: 0B51) is pleased to announce initial drilling results from the Gaspé Copper project, located in the

Gaspé Peninsula of Quebec. Infill drilling at the Mount Copper deposit has thus far demonstrated a limited extent of oxidation

and significant mineralization beyond the currently modeled (pit-constrained) Inferred Mineral Resource Estimate (“MRE”, see

April 28, 2022 press release). Results from sixteen holes are reported below, and all except DDH 30-0976 are from the Mount

Copper area on the southeast side of the deposit (see map).

Highlights include:

• Of the sixteen drill holes reported below, fourteen extended disseminated/stockwork copper-silver mineralization outside

the current pit-constrained resource model, including up to 170 metres in drill hole 30-0991 below the currently

designed pit floor. All fourteen holes ended in mineralization above or within the C Zone skarn horizon.

• Drill hole 30-0977, located 142.0 metres south of the modelled pit, intersected 375.3 metres grading 0.20% Cu and

1.31g/t Ag. This hole stopped in mineralization and can be extended if warranted.

• Drill hole 30-0985 intersected 528.0 metres grading 0.26% Cu and 1.72g/t Ag, including 46.5 metres grading 1.1%

Cu and 6.19g/t Ag in skarn-style disseminated mineralization in the C Zone . This hole extends 122.0 m below

the currently designed pit floor and stopped in mineralization.

Robert Wares, Chairman & CEO, commented: “We are very pleased with the initial results of our 30,000-metre drill program at

Gaspé Copper. Most of the reported results are from holes collared on top of Mount Copper, where historical drilling was

relatively scarce. We can now confirm that this area is mineralized with limited oxide copper and that the potential for further

expansion of the deposit appears to be significant as most of these holes ended in mineralization. With four drill rigs on site

currently, I am excited to build upon what is already the largest undeveloped copper resource in Eastern North America.”

Mineralization reported in the table below consists of disseminated and fracture-filling stockwork chalcopyrite mineralization

with minor molybdenite, hosted within potassic-altered hornfels (porcellanites) and skarn. Oxidized zones are minor and

appear to be associated with regional structures where they intersect the surface. Preliminary results indicate that the

oxide model used in the current MRE was most likely over-estimated and was overly conservative . The intersected

mineralized intervals are consistent with historical drilling results, they confirm continuity of mineralization and meet or exceed

expectations with respect to the current MRE for the Mount Copper deposit (see Map). Molybdenum assays received to date

indicate values generally equal to or less than 0.1% Mo.

About Osisko Metals

Osisko Metals Incorporated is a Canadian exploration and development company creating value in the critical metals space.

The Company controls one of Canada’s premier past-producing zinc mining camps, the Pine Point Project, located in the

Northwest Territories for which the 2022 PEA has indicated an after-tax NPV of $603M and an IRR of 25% based on the

current Mineral Resource Estimates that are amenable to open pit and shallow underground mining and consist of 15.7Mt

grading 5.55% ZnEq of Indicated Mineral Resources and 47.2Mt grading 5.94% ZnEq of Inferred Mineral Resources. Please

refer to the technical report entitled “Preliminary Economic Assessment, Pine Point Project, Hay River, Northwest Territories,

Canada” dated July 30, which has been filed on SEDAR. The Pine Point Project is located on the south shore of Great Slave

Lake in the Northwest Territories, near infrastructure, paved highway access, and has an electrical substation as well as 100

kilometres of viable haulage roads already in place.

The Company is also in the process of acquiring, from Glencore Canada, a 100% interest in the past-producing Gaspé Copper

Mine, located near Murdochville in the Gaspé peninsula of Quebec. The Company is currently focused on resource evaluation

of the Mount Copper Expansion Project that hosts a NI43-101 Inferred Resource of 456Mt grading 0.31% Cu (see April 28,

2022 press release). Gaspé Copper hosts the largest undeveloped copper resource in Eastern North America, strategically

located near existing infrastructure in the mining-friendly province of Quebec.
